Anyway, I decided the ESET suite was the best for my purposes and have been happy ever since. My main concern was the 'drive-by phishing' tests since Macs really don't pay much attention to Windows executables (*.EXE files) and I don't use my Windows laptop very often. Some passed each of the tests and others failed. I then installed them each individually, and thoroughly ran them through tests by going to the AMTSO web site. What I did was research all of the anti-virus suites both paid and free. The Multi-Device suite comes with all of the components for each of my devices (except, of course, my iPad and iPhone) and also covers my brother's Android phone. I also own a couple of iOS devices and my brother owns an Android phone.
My primary laptop is a MacBook Air with a secondary Windows 7 HP Pavilion laptop. I am a relatively new user of ESET Cyber Security Pro (for Mac) as I purchased the ESET Multi-Device Security suite at the beginning of February 2016.
